\ To all whom it may concern:

Be it known that I, IRA J. PADDocK, a citizen of the United States,residing at Percival, 1n thecounty of Fremont and State of Iowa, havenvented a new and useful Improvement in Motors, of which the followingis a specification.

My invention is in the nature of a novel construction of motor designedto be propelled by the pressure, momentum, flow, and expansion of anyelastic medium, such as steam or compressed air, water in motion, or thegases generated by explosive combustron.

It comprises an endless chain belt, which belt has articulated andfolding wings arranged within a tapering inclosing casing, which casingincloses one portion of the belt and its hinged wings and has an inletat its 20 small end for the steam or other fluid under pressure, so thatas the pressure of this fluid comes upon the wings they open and bear inthe travel of thebelt against the casing and by gradually unfoldingexpose their sur- 5 faces to the pressure of the fluid, all as hereline3 3 of Fig. 1.

inafter more fully described.

Figure 1. is a side elevation, partly in section. Fig. 2 is a transversesection on line 2 2 of Fig. 1. Fig. 3 is a transverse section on Fig. 4is an enlarged detail of the hinged and articulated wings as attached tothe belt. Figs. 5 and 6 are details showing modifications of the beltand its foldable wings.

In the drawings, A A represent two sprocket-wheels fixed to andrevolving with their shafts A A, from either or both of which the powermay be taken off in any suitable way.

4 B is an endless chain belt to whichon opposite sides are hinged thearticulated and folding wings w. These wings in one direction fold flatand lie close against the chain belt and in the other direction open toa rightangular position to the belt, in which rightangular position theyare stopped by suitable knuckle-lugs m, that preclude a further movementpast the right-angular position. The belt is composed of links Z, andthese 5 links are made longer than the wings and have holes Z throughthem beyond the edges of the wings when folded, which openings re ceivethe sprocket-teeth of the wheels and have also a further function, ashereinafter described.

C is the casing, which incloses one or bot-h runs of the belt betweenthe sprocket-wheels A A. At one end the casing has an inlet I for steamor other fluid under pressure and also a throatT, which gives entranceto the belt with its folded wings. From this point on toward the othersprocket-wheel the walls of the casing-at the top and bottom gradu allydiverge until they reach a point where the wings are fully unfolded tothe right-angularposition and here the casing as a tight inclosure ends.From this largest end of the casing, however, a plurality of parallelrods E extend from the top and bottom walls of the casing in convergentposition to a point close to the belt and near the rear sprocketwheel.These rods form a convergent exhaust grating, through which and at thesides the exhaust-steam or other fluid escapes, and the convergence ofthese rods causes. the wings as they travel between them tobe folded toa parallel position to the belt before traversing the rearsprocketwheel. After the wings traverse the rear sprocket-wheel they arereceived between parallel guide-rods R R and are held in the foldedposition until they reach the front sprocket-wheel to be again enteredinto the throat T of the casing.

. When the folding wings receive the first impact of steam, they openoutwardly and bear against the divergent walls of the casing, and asthey travel along they continually expand more and more until theright-angular position is attained. This secures an important result, inthat as they travel rearwardly they continually offer a greater pressurearea and as the chambers 1 2 3, &c., between the wings are ofcontinually-increasing volume the full benefits of the expansion of theelastic medium are obtained.

The openings Z in the links I of the chain belt, it will be seen, notonly serve to engage the sprocket-teeth, but also in case the belt isthe same width as the wings give passage for the steam from the upper tothe lower side of the belt, thus making its pressure efiective 1lgolthagainst the wings above and below the I do not confine myself to anyparticular means for attaching the articulated wings to the belt; but inFig. 4 I have shown one desirable form for doing so in which the samepintle-pin P which connects the links of the chain belt also passesthrough the tubular sockets of the wings above and below the belt, whilelugs m limit the unfolding range of movement to the right-angularposition.

It will be seen that, the wings of my motor form an endless series ofpistons or buckets, always traveling in the same direction and se-Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is I 1. A motor comprising an endless chainbearing folding wings, wheels distending the same and a casing having atapering form dicuring all the advantages of a rotary enginc:-vergingfrom the inlet end to the exhaust.

As a modification of the endless belt with foldable wings I mayconstruct it as in Fig. 5, in which the upper and lower win s w w areheld by jointed toggle-arms d, w 'ch arms when straightened out limitthe opening movement of the wings to the right-angular position and whenfolded allow the wings to lie fiat and parallel, or I may make it as inFig. 6, in which two wings to w are connected to links B B at 2 and 4and to link B at 3, so that the tension of the belt has a tendency toclose the wings, which latter are opened by the pressure of steamagainst the left-hand side. This construction in Fig. 6 would do awaywith plurality of rods E.

In pointing out the advantages of my motor I would state, first, thatthe application of the powerof the fluid is in a straight line; second,the flow is continuous and not pulsating; third, the leakage past anyone piston (folding pair of wings) is caught by the next piston; fourth,the parts all move with a continuous motion and there is no loss ofpower from stopping and starting, as in a reciprocating or oscillatingmotor; fifth, the steam or other elastic fluid is used expansively.

2. A motor comprising an endless chain bearing folding wings, wheelsdistending the same, a casing having a tapering form diverging from theinlet end to the exhaust, and an open converging exhaust-chamber.

3. A motor comprising an endless chain bearing folding wings with alimited articulation, wheels distending the same, and a divergent casinghaving a convergent exhaust end.

4. A motor comprising an endless chain belt having hinged wings withcoinciding sleeves on opposite sides of the belt said belt being formedof links whose pintle-pin also extends through the sleeves of the wingsand forms bearings for the same, wheels distending the belt and a casinginclosing the latter.

5. A motor comprising an endless chain belt having hinged wings, linksof greater length than the hinged wings and having openings in the samebeyond the edges of the wings when folded, wheels for distending thebelt, and a casing inclosing the latter.
